RICHARD \V. GRIMES AND JOHN FERN, OF SCRANTON, PENNSYLVANIA.

MINERS LAMP.

SPECIFICATION forming part of Letters Patent No. 280,738, dated July 3, 1883.

Application filed March 3], 1853.

To (LZZ whom it may concern:

Be it known that we, RICHARD WV. GRIMES and JOHN FERN, of Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Miners Lamps; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improvement in miners lamps.

Heretofore it has been a great source of annoyance and expense to miners to raise the wicks of their lamps, which they do in various ways, preferably by a sharp pin, in the absence of which they strike the lamp on their shoe, a stone, or any convenient article. Both of these methods are objectionable, the former because the necessary pin is often missing, and also because with this instrument a large portion of the wick is wasted, in that the wick cannot be raised evenly. The latter method is destroyed from the constant knocking it receives.

The object of our invention is to overcome this objectionable feature by providing an attachment which shall be adapted to raise the wick to any desired height, which may be applied to any ordinary construction of miners lamp, and which shall be simple in construction and of few parts; and with this object in view our invention consists in certain details of construction and combinations of parts, as will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figures 1 and 4 are views of an ordinary miners lamp in side elevation with our improvement attaehed thereto. Fig. 2 is a view of the same, showing our improvement detached therefrom. Fig. 3 is a view of the same, showing the slide removed.

A represents the body of the lamp, and B the spout. Around the spout B fits a sleeve, 0, provided on one side, at the lower end, with a flange, a. The spout B is provided near its lower end with a catch, 11, adapted to engage (No model.)

with the flange a, and thus hold the sleeve 0 in position 011 the spout. The sleeve 0 is also provided near its upper end with two parallel tubular guides, c c, of equallength, and running longitudinally the length of the sleeve. Near the lower end of this spout B, andin direct lines with the guides c c, are the guides c 0. Through these guides 12 0 run the arms D, which are bent at their upper ends in the form of a semicircle.

Between the guides c and c, and secured to or made integral with the arms D, are the lugs or stops d. Thus it will be seen that the 1011- gitudinal movement of the arms D is limited by the lugs d striking the guides c or c. It will also be observed that by turning the arms D so that the lugs cl will approach each other the curved ends of the arms D will move from each other, and that by pushing the lugs apart or away from each other the curved ends ap proach or pass each other. E represents. a slide provided with two oblique slots or guides, e. This slide is placed over the arms I) and guides c c, the lugs'd projecting through the oblique slots (2. A bolt or rivet, 71, passing through the slide E and traveling between the guides c c, is adapted to keep the slide E in po sition.

.Having described the construction of .our improvement, we will now set forth its operation.

We will suppose, for the purpose of illustration, that the parts are in the position shown in Fig. 1, the lamp being lit, and that it is necessary to raise the wick G. All that is necessary is to simply push the slide E toward the upper end of the sleeve, this movement, through means of the oblique slots formed in the slide E, separating or pushing away from each other the lugs (2, thereby bringing the curved ends of the arms D together, and thus grasping tightly the wick G. These h gs continue to separate until they strike the lower end of the oblique slots 6, where they are carried upward by the slide E. As the curved ends of the arms D have tightly grasped thewick G, the upward movement given to these arms also carries the wick in the same direction. As already described, the upward movement is limited by the lugs d striking the guides 0. After the wick has been raised the necessary distance, the slide is pressed down and, this movement bringing the lugs (I together until they strike the end of the slots, thus opening the curved end of the arms I). \Vhen the lugs strike the upper end of the oblique slots they are brought down with the slide E, thus placing the curved ends of the arms in position to take hold of the wick again. By simply raising the catch I) the sleeve may be slipped off of the spout B, thus leaving the ordinary lamp.

If desired, our improved device may be somewhat reduced in weight by making the sleeve in skeleton form, having sufficient surface for the attachment 0! the several neces sary parts.

()ur invention is equally well adapted for torches or other lamps or lanterns using a wick similar to the one herein shown. It is exceedingly simple in construction, is of few parts, may be applied to any ordinary miners lamp, maybe operated while the lamp is lit, and can be manuiactured at a small initial cost.

\Ve would have it understood that we do not limit ourselves to the precise construction herein shown and described. but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of our invention.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination, with a lamp having a wicktube, of devices secured to the tube and adapted to engage the wick above the tube for the purpose of elevating said wick.

2. The combination, with a lamp having a \vicktube, of movable arms, the upper curved ends of which embrace or partly embrace the wick beyond said tube for the purpose ol raising said wick.

3. The combination, with a lamp provided with a wick tube or-spout, of a movable sleeve adapted to lit on said wick tube or spout, and devices secured. to the said sleeve, and extending beyond the tube, whereby the wick may be raised.

4. The combination, with a lamp provided with a wick tube or spout, of a sleeve removably secured to said wick tube or spout, arms the upper curved ends of which embrace the wick above the spout, and a device for closing the upper curved ends of the arms on the wick and moving the arms and wick outward.

5. The (bmbination of a lamp and a sleeve removably secured to the spout thereof, said sleeve being provided with a slide and means connected therewith whereby the wick ot' the lamp may be raised.

(5. The combination, witha lamp anda sleeve rmnovably secured to the spout thereof, said sleeve being provided with guides, of arms adapted to move in said guides, and mechanism whereby said arms are operated to lift the wick of said lamp.

7. The combination of a lamp and a sleeve removably secured to the spout thereof, said sleeve being provided with guides, arms adapted to move in said guides, and having their upper ends bent in the form of a semicircle, and asl ide adapted to operate said arms,whereby the latter will close around the wick of said lamp and carry it upward.

S. The combination of a lamp and a sleeve rcmovably secured to the spout thereof, said sleeve being provided with guides, arms adapt:- ed to move in the guides, and having their upper ends bent in the form of a semicircle, said arms being also provided with lugs, and a slide placed over said guides and arms, and adapted by means of the lugs formed on said arms to close the curved ends of the arms around the wick and carry it upward.

9. The combination of a lamp and a sleeve removably secured to the spout thereof, said sleeve being provided with guides, arms mov ing in said guides, and having their upper ends bentin suitable term to grasp the wick of said lamp, a slide placed over said guides, and provided with two oblique slots or guides adapted to receive lugs formed on said arms, and a bolt or rivet passing through said slide, and moving between the guides formed on the. sleeve, said bolt or rivet being adapted to hold the slide in position.

10. The combination, with the lamp A and sleeve (1, adapted to be removably secured to the spout ii, of the guides c 0, arms 1), provided with curved ends and lugs or stops (I, slide 15, provided with oblique slots c, and bolt or rivet 11, all of the above parts combined and adapted to operate substantially as described.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
